TLDR
An index of the potential destructiveness of hurricanes based on the total dissipation of power, integrated over the lifetime of the cyclone, is defined and shows that this index has increased markedly since the mid-1970s, due to both longer storm lifetimes and greater storm intensities.
An Air-Sea Interaction Theory for Tropical Cyclones. Part I: Steady-State Maintenance
Abstract Observations and numerical simulators of tropical cyclones show that evaporation from the sea surface is essential to the development of reasonably intense storms. On the other hand, the
Optimal Sites for Supplementary Weather Observations: Simulation with a Small Model
Abstract Anticipating the opportunity to make supplementary observations at locations that can depend upon the current weather situation, the question is posed as to what strategy should be adopted
A Scheme for Representing Cumulus Convection in Large-Scale Models
  • K. Emanuel
  • Environmental Science, Physics
  • 1 November 1991
Abstract Observations of individual convective clouds reveal an extraordinary degree of inhomogeneity, with much of the vertical transport accomplished by subcloud-scale drafts. In view of these
Sensitivity of Tropical Cyclones to Surface Exchange Coefficients and a Revised Steady-State Model incorporating Eye Dynamics
  • K. Emanuel
  • Environmental Science, Physics
  • 15 November 1995
Abstract Numerical and theoretical models of tropical cyclones indicate that the maximum wind speed in mature storms is sensitive to the ratio of the enthalpy and momentum surface exchange
The dependence of hurricane intensity on climate

    Nature
  • 8 April 1987
Tropical cyclones rank with earthquakes as the major geophysical causes of loss of life and property1. It is therefore of practical as well as scientific interest to estimate the changes in tropical
Use of a Genesis Potential Index to Diagnose ENSO Effects on Tropical Cyclone Genesis
ENSO (El Nino–Southern Oscillation) has a large influence on tropical cyclone activity. The authors examine how different environmental factors contribute to this influence, using a genesis potential
An Air-Sea Interaction Model of Intraseasonal Oscillations in the Tropics
  • K. Emanuel
  • Environmental Science, Physics
  • 15 August 1987
Abstract We present a linear model of intraseasonal oscillations produced by the interaction of an atmosphere on an equatorial Beta-plane with a fixed ocean. Convection is treated as a means of
On large-scale circulations in convecting atmospheres
The dominant thinking about the interaction between large-scale atmospheric circulations and moist convection holds that convection acts as a heat source for the large-scale circulations, while the
An Air–Sea Interaction Theory for Tropical Cyclones. Part II: Evolutionary Study Using a Nonhydrostatic Axisymmetric Numerical Model
Abstract In Part I of this study an analytical model for a steady-state tropical cyclone is constructed on the assumption that boundary-layer air parcels are conditionally neutral to displacements
